Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral 20' indicates generally a dispenser constructed in accordance with the invention.

The dispenser 20 has a pair of spaced apart parallel side walls 21, 22 integrally connected by a top wall 23 and arcuate end walls 24, 25 respectively.

The side walls 21, 22 are connected by a pair of downwardly divergent walls 26 and a pair of upwardly divergent walls 27 joined together in the form of a diamond, as illustrated in Figure 1.

A pair of semi-spherical hollow bosses 28 are integrally formed on the side wall 21 in horizontal aligned relation and have a port 29 extending through the side wall 21 communicating with the space defined by the converging walls 26, 27 and the side walls 21, 22. A resilient suction cup 30 is provided with a head 31 supported in the spherical boss 28, as shown in Figure 2, to provide means of attaching the dispenser 211 to a relatively smooth surface or by engaging the suction cups 30 of one dispenser 20 with the suction cups 31) of another dispenser 20, as shown in Figure 4, to detachably connect a pair of dispensers 20 so as to permit stabilized floating thereof.

The arcuate end walls 24, 2.5 have integrally formed on the lower ends thereof flexible arcuate flaps 32 which can be swung to the dotted line position illustrated in the right hand portion of Figure 1 to provide an opening through which to fill the space between the converging walls 26, 27 and the arcuate end walls 24, 25 and top wall 23 with a plurality of cylindrical tablets 33.

The tablets 33 are a deodorizing and purifying chemical readily soluble in water and are held in the arcuate flap 32 to be contacted by water in which the dispenser 20 is floating or by water splashing into the flap 32 from a urinal, toilet or other device. As the tablets 33 dissolve in the flap 32 a new tablet 33 is permitted to descend into the flap 32 until the supply of tablets 3-3 in the dispenser 20 is exhausted.

Referring now to Figures 6 through 8, a modified form of the invention is illustrated comprising a dispenser 20a including a pair of parallel generally circular side walls 21a, 22a, arranged in spaced parallel relation and connected by a semi-cylindrical outer wall 24a and a cylindrical inner wall 26a arranged in concentric relation within the cylindrical wall 24a between the circular side walls 21a, 22a.

The outer semi-cylindrical wall 24a terminates at 25a on each side of the dispenser 20a and has integrally connected thereto an arcuate member 32a flexibly secured at 25a to the semi-cylindrical wall 24a to permit it to be moved to the dotted line position shown in the left side of Figure 6 to fill the dispenser 26a with chemical pellets.

A pair of semi-spherical hollow bosses 28a are integrally secured to the side wall 21a and are each provided with a central port 29a communicating with the space delineated by the side walls 21a, 22a and the cylindrical inner wall 26a. A suction cup 300 is secured to each of the hollow semi-spherical bosses 28a by means of a semi-spherical head 31a integrally joined to the suction cup 30a and engaging in the hollow boss 28a.

In the use and operation of the modification illus trated in Figures 6 through 8, the dispenser 20a is secured to an upright wall and the space between the side walls 21a, 22a and between the semi-cylindrical wall 24a and the cylindrical inner wall 26a is filled with chemical pellets by swinging the member 32a outwardly away from the cylindrical inner wall 26a. The pellets are then held in position by the members 32a and feed downwardly as they are consumed.

Referring now to the modification illustrated in the Figures 9 through 11, a dispenser 20b is illustrated having a pair of spaced apart parallel side walls 21b, 2217 connected by a pair of elongated spaced apart parallel end walls 24b and a pair of semi-cylindrical lower portions 25b. An upright inner wall 26b is positioned in parallel relation intermediate the side wall 24b and is provided with a semi-cylindrical lower portion 27b arranged concentrically to the semi-cylindrical portions 25b.

The side wall 21b is provided with a pair of semispherical hollow bosses 28b and a pair of supporting suction cups 30b are fastened thereto by means of integral heads 31b frictionally engaged in the semi-spherical hollow bosses 28b. The lower ends of the semi-cylindrical portions 25b are each provided with an arcuate member 32b which are flexibly connected to the semi-cylindrical portions 25b to permit them to be swung outwardly and downwardly when filling the dispenser 20b. The parallel end walls 241: each extend rearwardly beyond the side wall 21b forming a pair of guide flanges 2%, as best seen in Figure 9.

In the use and operation of the invention illustrated in Figures 9 through 11, the suction cups 30b are engaged with an upright portion U of a urinal securing the dispenser 29b in upright relation thereon. The dispenser 20b is filled with chemical tablets 331) by moving the members 32b away from the semi-cylindrical portion 27b in the same manner as disclosed in the prior modifications. Tablets 33b fill the space between the end walls 24b and the inner wall 26b and the space between the semi-cylindrical portions 25b and the semi-cylindrical portion 271) with the lowermost tablet 33b supported on the member 32b until it is completely dissolved. The guides 2% provide a guideway for the flow of water down the side wall 21b catching splashings from the urinal and directing them downwardly towards the members 3217 so as to insure a supply of water for the lowermost tablet 33b.

The modification illustrated in Figures 12 and 13 discloses a dispenser 20c having a pair of spaced apart parallel side walls 210, 220. The side walls 21c and 220 are connected by an arcuate top wall 230 and a pair of arcuate end walls 240 and downwardly and inwardly converging bottom walls 25c. The dispenser 20c has a pair of inner inverted V-shaped walls 260 extending between the walls 210, 22c and a second pair of V-shaped walls 270 joined integrally thereto and forming therewith a relatively flat diamond shaped configuration centrally in the dispenser 20c. One of the bottom walls 25c has an arcuate member 32c flexibly secured thereto to support chemical tablets 330 therein. The side wall 21c is provided with a pair of horizontally spaced hollow semi-spherical bosses 28c supporting a suction cup 300 in the same manner as in the preferred form of the invention.

The dispenser 20c operates identical to the dispenser 20 with the exception that a single member 32c is used to support the pellets 33c.

In Figures 14 and 15 another modified form of the invention is illustrated wherein a dispenser 20d is provided with a pair of spaced apart parallel circular side walls 21d, 22d connected by an outer semi-cylindrical wall 23d and a concentric inner cylindrical wall 26d.

A single centrally positioned semi-spherical hollow boss 28d is formed on the wall 21d and supports thereon a suction cup 3001 in the same manner as described above. An arcuate member 32d is flexibly secured to one end of the wall 23d to support pellets 33a! in dispensing position thereon. Adjacent the member 32d a pair of inverted V-s'haped guides 34 extend transversely of the wall 23d to guide the pellets 33d into the member 32d.

The operation of the dispenser 20d is identical to that of the dispenser 200.

In Figure 16 a semi-circular dispenser 202 is illustrated having a pair of arcuate member 32e secured to opposite ends thereof and a suction cup 30e mounted thereon in the usual manner.

The dispenser Zlle operates in the same manner as the dispenser 20a to dispense chemical purifying and deodorizing tablets where needed.

In Figure 17 a chemical dispenser 20; is illustrated with a cylindrical hollow body 21 supported on a bracket 22 and having an arcuate member 323 flexibly secured to the lower end of the hollow body 21 by means of an olfset extension 34]. The cylindrical body 21f supports a plurality of tablets 153 with the lowermost tablet 33f resting on the member 32f. In the use and operation of the invention the tablets 331 feed downwardly as the lowermost one is dissolved and new tablets are inserted by bending the member 32] out of the way.

Having thus described the preferred embodiments of the invention, it should be understood that numerous other structural modifications and adaptations may be resorted to without departing from the scope of the appended claim.
